Embodiment 1

[0027] Embodiment 1: The total length of a self-propelled two-rotation loader used in coal mines of the present invention is 31700mm, the total length of the tail slideway extending along the belt conveyor is 25000mm, and the effective stroke of the slideway is 22500mm; it can meet the 22m excavation scale per shift. like figure 2 , image 3As shown, taking continuous coal mining machine 11 as an example to form a roadway by mining coal twice, the roadway cross-section size width*height is 5500*4200m, and the continuous coal mining machine 11 is aligned with the right side of the coal seam 10 to start eating the first coal. A kind of self-propelled two-running loader used in coal mines of the present invention carries the coal hopper 6 and aligns below the scraper slide of the continuous coal mining machine 11. The first knife coal is eaten into 6-8m, and the power walking part 1 controls the coal-bearing hopper 6 to keep the position of the coal-bearing hopper 6 directly be...

Abstract

The invention discloses a self-walking two-conveying transfer machine for coal mine which comprises a power waling part, a two-conveying transfer part, an extension machine tail and an extension coalreceiving funnel; the power waling part is directly connected with the two-conveying transfer part; the extension machine tail is provided with a slideway; the extension coal receiving funnel is arranged on the extension machine tail; and the extension machine tail is directly connected with the two-conveying transfer part to be used for transferring coals on the two-conveying transfer part. The self-walking two-conveying transfer machine provided by the invention solves the problems of high cost and low efficiency of the existing coal mine roadway excavation.

Description

technical field [0001] The invention belongs to the technical field of power machinery, and in particular relates to a self-propelled two-run carrier for coal mines. Background technique [0002] At present, there are two methods of tunneling in coal mines: fully mechanized excavation and continuous mining. Fully-mechanized excavation is the excavation of fully-mechanized excavator. The rear of the fully-mechanized excavator is hung with a second-running loader, and the second-running loader transfers coal to the belt extending along the groove; continuous mining is a continuous coal mining machine followed by a shuttle car and a crusher. When the coal machine is excavated, the rear part is transported back and forth with a self-propelled shuttle car. The crusher breaks the coal mined by the continuous coal miner, and the shuttle car collects the coal mined by the continuous miner uniformly and transports it to the belt extending along the groove. These two excavation metho...
